Solution

O

Explanation:

Blood group O is called the universal donor because the red blood cells of type O do not have A or B antigens on their surface. This means that they can be safely transfused to people of any other blood group without causing an immune reaction. Therefore, individuals with blood group O can donate blood to any other blood group, making them universal donors.
